No. Don't "Drop Coco1/2...". At the very worst, simply recommend but don't 
*mandate* compatibility.

1920x1200 is no more difficult - and requires barely more resources - than 
256x192 in hardware.

The real problem that everyone has missed here is how you're going to map a 
huge chunk of video memory into the 6809 address space, and how you're going 
to move any decent portion of the screen around in real time.
